My dreams

I have seen patients suffering from chronic obstructive pulmonary disease (COPD) for many years. Once the disease develops into its late stage, generally there is no effective treatment. Too many patients only come to doctors when they cannot bear the tortures of this devastating disease any more, but that’s too late. Some others with early stage COPD don’t pay enough attention to it. Once the pulmonary function decreases and no action is taken, severe consequences result.
